Canada rolled to a 9-3 win over Germany in its opening game at the World Junior Hockey Championship on Wednesday.
Ryan Nugent-Hopkins, playing in the tournament for the first time, registered five points.
“We have such a skilled team up front and in the back end and it was good to see us come together like that,” Nugent-Hopkins told TSN.
Russia, playing in front of its home crowd in Ufa, Russia, survived Slovakia with a 3-2 overtime victory.
Albert Yarullin scored the winner in the extra period.
On Friday, Canada will face Slovakia, while Russia plays the United States.
Canada leads Pool B with three points. Russia is in second with two points, Slovakia has one point and the United States opens the tournament on Thursday against Germany.
Defending champion Sweden opened the tournament with a 4-1 win over the Czech Republic.
“I liked the way we competed,” Swedish coach Roger Ronnberg said, according to TSN. “I liked our PK, the way we were blocking shots, and the way we played without the puck, how we came back on the backcheck. It was good. Offensively, we can for sure still play better.”
Also on Wednesday, Finland beat Latvia 5-1 to pick up three points in Pool A.
Miro Aaltonen scored twice and had one assist for the Finns, but left the game after a third-period collision.
“His tournament is over because his ankle is very bad,” Finnish coach Harri Rindell said, according to TSN. “He was so depressed because he really wanted to play and he is in great shape. That’s hockey, unfortunately.”
Rindell also said that Aaltonen might require surgery.
Switzerland will open the tournament on Thursday against Latvia. On Friday, Finland faces the Czech Republic and Sweden plays Switzerland.
